PURPOSE: An apparatus for exchanging a jig is provided to effectively exchange a trolley as a lift plate ascends and descends with the movement of the a slide plate. CONSTITUTION: An apparatus for exchanging a jig comprises a trolley(10), a base plate, a slide plate(40), a linear actuator(50), a lift plate(60), and a plurality of main lift cylinders(70). A jig(20) is loaded on the trolley. The trolley is moved by a plurality of wheels(14). The base plate comprises a first position for exchanging the trolley and a second position for work using the jig. The slide plate is installed on the upper part of the base plate, and linearly moved in between the first and second positions. The linear actuator linearly moves the slide plate in between the first and second positions. The plate is installed in the trolley, and placed above the slide plate. The lift plate moves up and down in between a third position, in which the trolley is placed on a floor and a fourth position, in which the trolley is lifted from the floor. The plurality of main lift cylinders is installed between the slide plate and the lift plate, and lifts the lift plates in between the third and fourth positions.
